To all whom t may concern:

Be it known that we, STEFAN Scrmnnnn and lilriioraursl SCHREDER, subjects of Hungary, residing at Cleveland, in the county of Cuyahoga and State of Chio, have invented certain new and useful lmprovements in Gras Heating-Stoves, of which the following is a specification.

Cur invention relates to an improvement in gas heating stoves, and the object of the invention is to provide a cylindrical stove in which a circular column of flame is adapted to be maintained by a gas burner removably seated on a base plate and held in an upright position by the top plate of the stove and centrally situated within a sheetmetal radiating shell which forms the main body of the stove. This shell and the top and bottom plates and the upright burner tube when united together constitute acomplete stove which is inexpensive to manufacture, easily assembled, and capable of producing a large amount of heat within a relatively small space.

ln the accompanying drawings, Figure 1 is a vertical section centrally through our improved stove. Fig. 2 is a cross section in plan on line 2-2, Fig. 1. Fig. 3 is a bottom view of the stove with the legs removed showing the gas supply pipe and the 'central air intake opening for the burner.

Structurally considered, the stove comprises a cast-iron base-plate 2 having an annular flange 3 forming a depending border portion to which separate legs 4 are bolted to support the plate above and apart from the floor. A number of openings 5 in plate 2 permit air to pass upwardly into the combustion and heating space above the plate 2 within the cylinder or sheet-metal body 7 which is sleeved within and bolted to an annular vertical Hange 8 on the base plate 2. An upright circular fiange 9 centrally upon f the upper side of plate 2 provides a seat or socket 10 opposite a 'central air opening 11 in the plate, and an elbow 12 extends into opening 11 and a gas supply 'pipe 13 connects with the elbow. Pipe 13 is clamped against two spaced lugs 11i- 14e which depend from the bottom side of the plate and. the clamping means comprises a saddle or yoke 15 and stove bolts 16, see Fig. 3. rlhe outer end of suppl. pipe 13 is provided with a valve 17 and ew 'l2 has a sere plug 18 .with a central vertical orifice through which the gas is projected upwardly into the flaring bottom end of an upright burner tube 19 which is seated within socket 10 above opening l1. A series of radial ribs 2O cast integral with the bottom side of'plate 2 centers the elbow l2 within opening 11. Burner tube 19 is relatively long and extends the full height of the stove. As shown it is of approximately the same length as cylinder 7 and provided with circular rows of gas openings or perforations 21 at different elevations, the first or lower row of openings occurring a short distance above the base plate and thence at frequent intervals to the top or upper end of the tube. The perforations in one row are preferably offset or staggered in respect to the perforations in the ,adj acent rows, and in operation a circular column of flame is produced which cncircles the burner opposite the circular radiating wall of cylinder 7, beginning approximately opposite the lower row of openings 21 which slightly exceed in number the perforations in they rows higher up on the tube.

Burner tube 19 has a reduced extension 22 at its upper end which is seated within a socket 23 at the bottom side of the fla-t round top plate or cover 24C of the stove, and this plate also has a depending annular flange 25 fitted upon and bolted to the upper end of cylinder 7. Cover plate 24 is also provided at its upper end with a flanged stove pipe opening 26 through which the products of combustion are discharged, and cylinder 7 -has a lighting opening in its side opposite the burner tube and a sliding door 28 with an isin-glass window 29 is mounted opposite said opening.

What we claim is:

1. A gas heating stove, comprising a base plate having a central air opening and seat for a tubular burner, a gas supply connection adapted to discharge into said opening, a tubular burner having a series of openings radially and longitudinally thereof and seated at its lower end upon said seat, an inclosing cylinder extending upwardly from said base plate to the same height as said burner, a cover plate for said cylinder having a central socket at its bottom side and a flanged stove pipe opening at its top, and .said burner tube having' an extension cond fined Within said socket to hold the tube lcentrally in an upright position Within said cylinder.

2. A gas heating stove, comprising a flanged base plate having a central air opening surrounded by an annular socket and seat for a separate burner tube, a gas supply pipe detachalolyl secured to the bottom side of said plate inV discharge relation centrally to said air opening, a separate burner tube having a multiple number of gas oriice's at spaced intervals between its opposite ends and the lower end of said burner being open and seated Within said socket,

a single cylinder connected With said flanged 15 base plate and inclosing said burner tube, and a flat cover plate having a depending iange connected With said cylinder and a depending 'socket portion centrally adapted to hold the upper end of said burner tube, 20 Said tube having gas discharge orifices adjacent the bottom side of said cover plate. Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 21st day of February, 1920.
